The news service ran a report on the Hollywood actor apologising to Sunderland football fans after Queens Park Rangers lost 3-0 at Loftus Road, London.
QPR fan Ferrell, who was in the crowd to watch the match, had said: "Sunderland – oh, the tears of sorrow you’re going to experience tonight dripping down your face into your mouth drowning you in sorrow, I can only imagine."
The BBC then ran a story with the headline “QPR fan and actor Will Ferrell apologises for mocking Sunderland fans."

It quoted a tweet from the account @OfficialWilllF which read: "Haway man, sorry @SunderlandAFC", alongside a screenshot of his "tears of sorrow" comment.
The BBC said: “In a BBC News Online article, we incorrectly stated QPR fan and actor Will Ferrell apologised for mocking Sunderland fans. A quote was taken from a verified Twitter account, but it was not made by the actor. We have removed the article in its entirety since it was based wholly on the apology.”
While the account has been verified by Twitter with a blue tick the BBC failed to recognise it is a parody account.
The Twitter profile has a picture of Ferrell and says it belongs to "Will Ferrell, Comedian, actor, impressionist (parody)."
Since Elon Musk took over the social media platform in 2022 he introduced premium service Twitter Blue, whereby users can purchase a blue tick verification for a monthly or annual subscription.
The blue tick was previously issued to users on application as proof of an 'official' account, or dependant on the number of followers.
Elf star Ferrell is big soccer fan and partly owns LAFC in Los Angeles.
He has been on a football tour of the UK, attending matches around the country, including Wrexham against Wealdstone, Manchester City's game with Aston Villa and Liverpool Vs Everton.
He regularly takes part in charity football competition Soccer Aid.
